From Bull in China: If you’re only going to own one jigger, this bell jigger gets our vote. The ergonomic design makes it easy to use for as long as you’d like. Thanks to its internal markings, you can easily measure anything from .25 oz to a full 2 oz. We believe it’s the most versatile jigger to have behind the bar or at home. Larger side is 2 oz (with internal marking at 1.5oz). Smaller side is 1 oz (with internal markings at .25, .5, and .75oz). All finishes have food safe stainless steel interiors. Copper.
